The Windows 10 Start menu was a reintroduction of the traditional start menu not seen by consumers since Windows 7. The Start button is in the bottom left corner of the Desktop. In Windows 8, Microsoft introduced the Start menu, which was intended to be easily scalable to a smartphone screen, but it was deeply unpopular with computer users. To try to please everyone, Windows 10 has both the Start menu and the Start screen, with the Desktop and Start menu as the default display. You can switch between the two, but you have to set up the Start screen first.
